Description

Technical Field

[0001] This invention relates to the field of air ring devices for the two-bubble process, and in particular to a special air ring for a two-bubble process production line. Background Technology

[0002] The air ring is a crucial component of the blown film unit, responsible for cooling and shaping the inflated film bubble. The air ring has a circular structure, cast from aluminum alloy, and is structurally divided into several parts: air inlets, air exchanger body, rotating body, and upper and lower lips (air outlets). There are an even number of air inlets, evenly distributed on the lower part or side of the air ring, connected to the blower's air distribution unit via air ducts. The air ring body is a hollow shell with a labyrinthine cross-section, and the air outlet is located between the upper and lower lips, from which the airflow is blown out in a 360-degree arc.

[0003] In the two-bubble process production line, the film belt needs to undergo a bubble-forming process after drying in the oven. At this time, the overall temperature of the film belt is relatively high, and it needs to be cooled down in time. Existing two-bubble process production lines mostly use the above-mentioned conventional air ring structure to cool down the film belt. However, the following problems exist in the actual production process: 1. When the film belt exits the oven, the existing air ring structure cannot achieve instant cooling of the film (bubble) belt, which makes it difficult to control the shrinkage of the film belt and affects product quality. 2. The existing air ring structure blows air unevenly, which cannot achieve uniform cooling of the periphery of the membrane (bubble) belt. This results in uneven thickness of the blown membrane bubble with large deviations, which cannot achieve fine control of the membrane bubble and affects subsequent production and use. Summary of the Invention

[0004] The purpose of this invention is to provide a special air ring for a two-bubble process production line. Its overall structure is scientifically designed and adopts a two-stage synergistic cooling structure design, which can meet the instantaneous cooling of multiple membrane belts. At the same time, it can uniformly disperse the cooling air, ensuring uniform cooling of the membrane bubble periphery and realizing fine control of the membrane bubble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A special air ring for a two-bubble process production line includes a fixed base, a fixed frame, an air ring housing assembly, a uniform cooling component, and an adjustable cooling component. The fixed frame consists of a fixed plate and a frame, with the frame installed around the perimeter of the fixed plate and integrally connected to it. The fixed base is installed on the outer side of the fixed plate using mounting bolts. A circular through hole is machined in the fixed plate. The air ring housing assembly is installed on the inner side of the fixed plate using mounting bolts. A first mounting step and a second mounting step are formed on the air ring housing assembly. The uniform cooling component is assembled on the first step of the air ring housing assembly and is securely installed together with it. The adjustable cooling component is installed on the second step of the air ring housing assembly and is securely installed together with it. An adjustable cooling air duct is formed between the uniform cooling component and the adjustable cooling component. A uniform cooling air duct is formed within the uniform cooling component.

[0006] The aforementioned air ring housing assembly includes an air inlet, a vortex air inlet channel, a housing base, an outer shell, and an inner shell. The housing base is mounted on a fixed frame by mounting bolts. The outer shell and the inner shell are mounted on the housing base. The outer shell and the inner shell are fixedly connected to the housing base as an integral structure. An air inlet channel is formed between the outer shell and the inner shell. Four sets of vortex air inlet channels are installed on the outer tangent of the air inlet channel for inputting air into the air inlet channel. The first mounting step and the second mounting step are formed on the housing base.

[0007] The four sets of vortex air intake channels are evenly distributed on the outer tangent of the air intake channel. An air inlet is installed at the inlet of the vortex air intake channel. The air inlet is installed together with the vortex air intake channel. After the air enters the vortex air intake channel through the air inlet, it forms a vortex wind in the air intake channel.

[0008] The uniform cooling assembly includes an upper air ring, a middle air ring, and a lower air ring. The upper air ring is a circular structure, consisting of an annular mounting part and an annular guide part. The lower outer circle of the annular mounting part is mounted on a first mounting step by mounting bolts. The annular guide part is mounted in the middle of the annular mounting part and is fixedly connected to it. An annular guide groove is machined on the outer circle of the annular guide part for guiding the cooling airflow. A lower mounting platform is machined on the lower side of the annular guide part, and an upper mounting platform is machined on the upper part of the lower air ring. The middle air ring is installed between the lower and upper mounting platforms to homogenize the cooling airflow.

[0009] The wind ring sleeve is a circular structure made of foamed copper. Inside the wind ring sleeve, there are breathable honeycomb-shaped holes. The honeycomb-shaped holes can homogenize the airflow. The cooling airflow sent into the uniform cooling air duct can be homogenized through the honeycomb-shaped holes in the wind ring sleeve and then flow out to perform a first-stage uniform cooling operation on the membrane bubble.

[0010] The lower sleeve of the air ring includes a lower sleeve body and a guide cone. The guide cone is installed on the lower sleeve body and is fixedly connected to the lower sleeve body as an integral structure. A uniform cooling air channel is formed between the lower sleeve body and the guide cone. Four sets of mounting holes are evenly distributed on the circumference of the lower sleeve body. An air inlet connector is installed in the mounting hole and the air inlet connector is connected to the cooling airflow. The guide cone has a smooth conical surface. An inclined platform is machined on the outer circle of the middle sleeve of the air ring. The cooling airflow can converge to the lower side of the outer circle of the middle sleeve of the air ring under the synergistic effect of the smooth conical surface and the inclined platform to achieve high-pressure converged gas. The high-pressure converged gas flows out through the breathable honeycomb-shaped small holes formed inside the middle sleeve of the air ring to perform primary uniform cooling of the membrane bubble.

[0011] The adjustable cooling assembly includes a louver body, a louver mounting bracket, a ring cover, and a ring adjustment plate. The louver body is an annular structure. The upper part of the louver body is installed at the bottom of the louver mounting bracket and is fixedly connected to the louver mounting bracket. N sets of louver plates are machined on the louver body, and cut flow channels are formed between the louver plates. The louver mounting bracket is installed on a second mounting step through the louver body. The louver mounting bracket is fastened to the inner shell, and a flow cavity is formed between the louver mounting bracket and the inner shell. A mounting platform is provided on the louver mounting bracket. The ring cover is installed on the mounting platform by mounting bolts. The ring adjustment plate is installed on the ring cover and can be moved and adjusted on the ring cover to adjust the cooling airflow direction. An adjustable cooling air duct is formed between the ring cover, the ring adjustment plate, and the ring cover.

[0012] Furthermore, an annular step is provided on the upper cover of the air ring, and an internal thread is machined on the inner wall of the annular step. An external thread that matches the internal thread on the inner wall of the annular step is machined on the outer circle of the air ring adjusting plate. The air ring adjusting plate is movably and adjustablely installed on the upper cover of the air ring through a threaded engagement.

[0013] Furthermore, an annular step is provided on the upper cover of the air ring, and a clamping threaded hole and a mounting blind hole are machined on the annular step. A clamping through hole corresponding to the clamping threaded hole and a mounting threaded hole corresponding to the mounting blind hole are machined on the air ring adjusting plate. A clamping bolt is installed in the clamping threaded hole and the clamping through hole, and an adjusting screw is installed in the mounting blind hole and the mounting threaded hole. The adjusting screw can adjust and limit the distance between the upper cover of the air ring and the air ring adjusting plate. After the clamping bolt passes through the clamping through hole, it is turned into the clamping threaded hole to clamp the air ring adjusting plate and the upper cover of the air ring together.

[0014] Furthermore, an annular step is provided on the upper cover of the air ring, and an adjustment threaded hole is machined on the annular step.

[0015] The beneficial effects of this invention are as follows: The overall structural design of the air ring for a two-bubble process production line is scientific, and compared with the existing air ring structure for two-bubble process production lines, it has the following technical features and advantages: 1. Two-stage cooling of the membrane bubble can be achieved. Compared with the existing air ring structure used in the two-bubble production line, the present invention can achieve two-stage cooling of the membrane bubble. Specifically, a uniform cooling component and an adjustable cooling component are designed in the whole structure. When in use, the uniform cooling component can achieve the first-stage cooling effect of the membrane bubble through the uniform cooling air channel and the synergy of the foam copper. When in use, the adjustable cooling component can achieve the second-stage cooling effect of the membrane bubble through the adjustable cooling air channel, thereby ensuring that the membrane bubble is in a controllable shrinkage state. 2. Uniform cooling of the membrane bubble's periphery can be achieved; When the special air ring for the two-bubble production line of the present invention is in use, the cooling air can enter the inner sleeve of the air ring through the uniform cooling air channel. The inner sleeve of the air ring is a circular structure made of foamed copper material. Breathable honeycomb-shaped holes are formed inside the inner sleeve of the air ring. The honeycomb-shaped holes can homogenize the airflow. The cooling airflow sent into the uniform cooling air channel can be homogenized through the honeycomb-shaped holes in the inner sleeve of the air ring and then flow out to perform a first-stage uniform cooling operation on the membrane bubble, thereby ensuring that the thickness of the membrane bubble is uniform. 3. It can achieve homogenization and stabilization of cooling airflow and adjustment of airflow direction; When the special air ring for the two-bubble production line of the present invention is in use, the air grid mounting bracket is fastened to the inner shell and a flow cavity is formed between the air grid mounting bracket and the inner shell. The cooling airflow can be homogenized and cut in the flow cavity through the cutting channel formed between the air grid plates. The homogenized and cut airflow flows out through the adjustable cooling air channel to perform secondary cooling and cooling of the film bubble. At the same time, the air ring adjustment plate can be moved and adjusted on the air ring cover to adjust the cooling airflow direction. Attached Figure Description

[0025] The installation and use process of the special air ring for a two-bubble process production line according to the present invention is as follows: I. The installation process is as follows: First, the installer can install the fixed frame 2 of this invention on the fixed base 1, and then install the air ring housing assembly 3. The specific installation process is as follows: the housing base 33 can be installed on the fixed frame 2 with mounting bolts, and the outer shell 34 and inner shell 35 can be installed on the housing base 33. At this time, an air inlet channel is formed between the outer shell 34 and the inner shell 35. Four sets of vortex air inlet channels 32 are evenly distributed on the outer tangential surface of the air inlet channel for inputting air into the air inlet channel. At the same time, a device for air intake is installed at the inlet of the vortex air inlet channel 32. The air inlet 31 is then installed, followed by the installation of the uniform cooling assembly 4. Specifically, the upper sleeve 41 of the air ring is installed first. The upper sleeve 41 consists of an annular mounting part 411 and an annular guide part 412. The annular mounting part 411 is used to support and mount the annular guide part 412. During installation, the lower outer circle of the annular mounting part 411 is mounted on the first mounting step using mounting bolts. The annular guide part 412 is installed in the middle of the annular mounting part 411 to collect and guide the cooling airflow. The outer circle of the annular guide part 412 is machined... An annular guide channel 413; simultaneously, a lower mounting platform is machined on the lower side of the annular guide section 412, and an upper mounting platform is machined on the upper part of the lower sleeve 43 of the air ring. The lower sleeve 43 of the air ring includes a lower sleeve body 431 and a guide cone 432. During installation, the guide cone 432 is installed on the lower sleeve body 431 and fixedly connected to the lower sleeve body 431 as an integral structure. The middle sleeve 42 of the air ring can be installed between the lower mounting platform and the upper mounting platform. Finally, the adjustable cooling component 5 is installed. Specifically, the upper part of the air grille 51 can be fixedly installed on the bottom of the air grille mounting bracket 52. 160-180 sets of air grating plates are processed on the body 51, and cutting channels 55 are formed between the air grating plates to uniformly cut the airflow. During installation, the air grating mounting bracket 52 is installed on the second mounting step through the air grating body 51. The air grating mounting bracket 52 is fastened to the inner shell 35 and between the air grating mounting bracket 52 and the inner shell 35. The air ring cover 53 is installed on the mounting platform with mounting bolts. The air ring adjusting plate is installed on the air ring cover 53 and can be moved and adjusted on the air ring cover 53 to adjust the cooling airflow direction. Thus, the installation process of the present invention is completed. II. In practical use, this invention achieves two-stage uniform cooling of the membrane bubble through the coordinated operation of the uniform cooling component 4 and the adjustable cooling component 5. Regarding the uniform cooling component 4, the air inlet 44 can be connected to an external cooling airflow. The cooling air can enter the air ring sleeve 42 through the uniform cooling air duct 7 from the air inlet 44. The air ring sleeve 42 is a circular structure made of foamed copper. Breathable honeycomb-shaped pores are formed inside the air ring sleeve 42. These pores can homogenize the airflow. At this time, the cooling airflow delivered into the uniform cooling air duct 7 can pass through the honeycomb-shaped pores inside the air ring sleeve 42. After homogenization by the honeycomb-shaped orifices, the airflow flows out to perform a primary uniform cooling operation on the membrane bubble, thereby ensuring that the thickness of the membrane bubble is uniform. It should be noted that, in order to ensure the passage of the cooling airflow in the honeycomb-shaped orifices, the guide cone 432 is designed with a smooth conical surface. At the same time, a ramp 421 is machined on the outer circle of the air ring sleeve 42. In use, the cooling airflow can converge to the lower side of the outer circle of the air ring sleeve 42 under the synergistic effect of the smooth conical surface and the ramp 421 to achieve high-pressure converged gas. The high-pressure converged gas can flow out through the breathable honeycomb-shaped orifices formed inside the air ring sleeve 42 to perform a primary uniform cooling operation on the membrane bubble. Regarding the adjustable cooling component 5, during use, the cooling airflow enters the air intake channel within the vortex air intake channel 32 through the air inlet 31 and forms a vortex airflow within the air intake channel. The air grid mounting bracket 52 is fastened to the inner housing 35, forming a flow cavity between the air grid mounting bracket 52 and the inner housing 35. The flow cavity is a component of the air intake channel. The cooling airflow within the flow cavity is homogenized and cut through the cutting channel 55 formed between the air grid plates. The homogenized and cut airflow flows out through the adjustable cooling air duct 6, thus performing secondary cooling of the membrane bulb. Simultaneously, the air ring adjustment plate can be adjusted on the air ring cover 53 to adjust the cooling airflow direction. Specifically, when the air ring cover 53 is adjusted downwards, the cooling airflow through the adjustable cooling air duct 6 disperses away from the outer periphery of the membrane bulb; when the air ring cover 53 is adjusted upwards, the cooling airflow through the adjustable cooling air duct 6 disperses closer to the outer periphery of the membrane bulb. The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
